Sine qua non Radiology-Pathology


Seromucinous hamartoma (SMH) is a rare benign epithelial proliferation occurring in the sinonasal tract. The clinical, radiographic, and histologic appearance of SMH may mimic several benign and malignant entities. Presented is a novel case, with a review of the literature focused on potential histologic diagnostic pitfalls.
